Diversidad genética de Oreopanax xalapensis (Araliaceae) en Los Altos de Chiapas

Abstract: 1Autora para correspondencia: lruiz@ecosur.mx Resumen: La diversidad genética de una especie determina su capacidad de respuesta a los cambios ambientales, por lo que su conocimiento puede ser de importancia para el diseño de estrategias de restauración de bosques. En este estudio se analiza la diversidad y estructura genética de cinco poblaciones de Oreopanax xalapensis en Los Altos de Chiapas. Esta especie se está utilizando en prácticas de restauración del bosque mesófilo de montaña en la región, pero se de… Show more

“…The samples of O. xalapensis from ESS, MSS, and LSS were taken at a fine scale geographic distribution (around 350 m lineal distance), inferring that the seeds are easily dispersed among and between the different successional stages, which likely contributes to the genetic homogenization among populations (Sezen, Chazdon, & Holsinger, 2005). Seed dispersal in O. xalapensis is highly mediated by mobile animals such as birds, bats, and small rodents (Ruiz-Montoya et al, 2011), which may increase the gene flow, thereby preventing genetic differentiation (Hamrick, Murawski, & Nason, 1993). Therefore, we were unable to establish the relationship between population size and genetic diversity across successional stage.…”

“…Therefore, we were unable to establish the relationship between population size and genetic diversity across successional stage. At a larger geographical scale (>20 km), O. xalapensis display differentiation among populations of the Highland of Chiapas, mainly driven by fragmentation of MCF (Ruiz-Montoya et al, 2011).…”
